Prolonged experimental CD4+ T-cell depletion does not cause disease progression in SIV-infected African green monkeys
Abstract
HIV infection results in the depletion of CD4+ T cells overtime and the loss of coordinated cellular immunity, but how this corresponds to the SIV infected African Green Monkey (AGM) model of non-progressive disease is not known. Here the authors assess the impact of experimental CD4+ T cell depletion in AGM and show that lack of disease progression and resistance to AIDS in this model are independent of CD4+ T cell loss.
